Dependent Pair of Events: A

Independent pairs of events: B,C,D,E

Step-by-step explanation:

Lets look at each pair one by one..

A. the selling price of a product and its manufacturing cost

We can clearly see that the selling price of a product is always determined on the basis of it's manufacturing cost.

So A is a pair of dependent events.

B. your pulse rate and your friend’s pulse rate

The pulse of rate of one person has nothing to do with the pulse rate of another person.

So B is a pair of independent events.

C. the price of a cell phone and the price of a TV

The price of cell phone and Tv are not related to each other at any level..

So C is a pair of independent events.

D. your calorie intake and your friend’s calorie intake

One person's calorie intake is not related or dependent on any other person's calorie intake.

So D is a pair of independent events.

E. the distance of your home from school and your friend’s home from school

The distances of one person's home from school doesn't affect the distance of another person's home from school.

So E is a pair of independent events..
